Hello sir, I am from bangladesh, 13th aug 2018 I did a sex with prostitute having condom only for 2 minutes. Then I dispose the condom into commode and flashed it. Someday later gradually I had been experiencing sore throat, muscle pain, headache, fever for 20 days. Now 5.5 months have finished still I have those symptoms. During this time I have tested elisa ab/ag test for 4 times (1.5,3,5,5.5 months. All are negative/non reactive. But I am worried. If there any chances the virus enter my body but do not show the antibody. Pls advise me.
